NITED STATES JEAN B. ROLLAND, or PARIS, FRANCE.

TRAVELER FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 275,946, dated April 17, 1883,

Application filed April 12, 1882. (No model.)

To all whom it may concern: 7

Be it known that I, JEAN BAPTISTE R01.- LAND, a citizen of the Republic of France, at present residing in Paris, have invented a new and .Improved Traveler for Bing-Spinning Frames, of which the following is a specificascribed and claimed, reference being bad to.

the accompanying drawings, in which- Figure 1 is a sectional elevation of a ring supporting my traveler, shown in elevation. Fig. 2 represents the common traveler, a thread thereon, and a section of part of aring. Fig. 3 shows another form of my traveler. Fig. at shows another modification of my traveler, adapted to a ring having vertical flanges.

A represents that end or hook of the traveler which is within the ring.

A represents the end or portion of the traveleroutsideofthering. Thesetwohookedends, joining at the middle, form the whole of the old style or common traveler shown in Fig. 2.

0 represents the ring.

B represents an addition to the common traveler, which constitutes my invention. WVhen adapted to be used with the common horizontally-flanged ring shown in Fig. 1 this addition B,preferably made of steel wire, will be secured at one end to the inner curve, A,of the traveler AA, forming apart thereof. Its direction from its point of attachment is upward and outward, forming at z' a somewhat sudden bend outward,its outer end beingbent downward and back toward the ring, forming a book. This book is for the double purpose of adding weight at this point and of preventing the thread from being disengaged therefrom by centrifugal force. The thread g comes from the feed-rolls in the direction i, passes once around the addition B of the traveler, then beneath the hook A, thence in the direction g tangent to the bobbin.

With the common traveler there are three causes bearing on the tension of the thread being spun, viz: first, friction of the thread centrifugal force is in the direction h.

in drawing through the traveler in being wound on the bobbin second, friction of the traveler on the ring-race; third, the centrifugal force of the traveler. tained is to so balance these forces, acting in some respect in opposition to each other, as to cause an even tension upon the thread atall times, so that whether winding at the top, the middle, or bottom of the bobbin, or upon a full or an empty bobbin,the thread will be evenly and smoothly spun.

WVith the common traveler the action of This would be fairly opposed by the strain of the thread at the end g, and were there no other forces acting than these two the weight of the traveler and the speed of the spindle might be adapted to the size of the thread so perfectly that the traveler thus acted upon would revolve on the ring almost without touching it; but I find that the strain of the other end of the thread in the direction i tends to change the resultant strain to a line of direction between 9 and i, so that a coun- The object to be atterpoise is required to produce the result v sought. This 1 have supplied in the part B, whose centrifugal force is in the direction f.

Fig. 3 shows the part B not so long as in Fig. 1 and the bend am not so abrupt. The farther outward the bend t'is made in the part B the more advantage the thread will have in holding up the traveler; but the farther outward the hook end of the partB is extended the more advantage or strain the traveler will have on the thread.

Fig. 4 shows means of adapting the same principle of construction to a traveler to run upon a ring having vertical flanges.

What I claim as my invention, and wish to secure by Letters Patent, is-

A traveler for ring-spinning frames, consisting of a piece of metal bent at its ends A A in the usual form, having a piece, B, secured thereto at the inner upper curve and extending upward and outward, and bent at its outer end into a downward hook, as shown and described.
